You know what, I think it's all a good thing.
Sure, there is going to be a load of crap products pop up and people trying to cash in on the trend but, if you can BBQ properly, people will notice the difference.
You'll be seen as some kind of wizard when you pull out a load of perfectly cooked ribs and pulled pork that knock the socks off what they've tried from Asda.
Many foods have gone through this trend. Look at Thai. Everyone suddenly had green curry on their menus and in most cases, it was rubbish. At the other end of the chain, there are some amazing Thai restaurants around. Also, I can now buy fresh Thai ingredients on my small island 8,000 miles away from Thailand.
More awareness is a good thing. It means more charcoal, equipment and BBQ meat cuts in shops and an overall bigger marketplace if you're in the BBQ business.
